Henan Municipality (河南, i.e., the region of the Tang eastern capital Luoyang). He would later serve as deputy minister of census (戶部侍郎, Hubu Shilang) and then the deputy minister of defense (兵部侍郎, Bingbu Shilang), also serving as the director of the salt and iron monopolies. Chancellorship In 872, by which time Zhao Yin was referred to as deputy minister of justice (刑部侍郎, Xingbu Shilang) and director of taxation, then-reigning Emperor Yizong (Emperor Xuānzong's son) gave him the designation Tong Zhongshu Menxia Pingzhangshi (), making him a chancellor de facto, as well as deputy minister of census.

After chancellorship In 875, after some 69 officers of Zhenhai Circuit had battlefield accomplishments, Zhao Yin gave them honorific titles, but no increases in food or clothing stipends. This displeased them, who appealed the lack of increase, but their appeals were denied. They, thereafter, under the leadership of Wang Ying, rebelled and pillaged the region. As a result of what was considered mishandling of the situation by Zhao, he was relieved from
